Thanks, that makes sense of course, except that I want to display help for the chart functionality, i.e. right-clicking on the chart displays a popup of ChartFX options like opening the data editor, displaying the toolbar, legend box etc... There must be a help file that describes how to use the functions and toolbar options of a ChartFX chart, isn't there?
If I have that file, then the app can handle the InternalCommand event and open the file itself, that's fine.
